[TechGage] AMD’s Radeon VII GPU Will Not Support Uncapped Double-Precision (FP64)

https://techgage.com/news/radeon-vii...4-performance/

Quote:
We reached out to AMD’s Director of Product Marketing Sasa Marinkovic to inquire whether or not the FP64 inclusion was real, and were told quite simply that “Radeon VII does not have double precision enabled.” That means instead of delivering 6.7 TFLOPS of FP64 like the MI50, Radeon VII will be closer to ~862 GFLOPS (it’s 1:16 with single-precision like RX Vega).

flash it into an MI50!

trolling an adult is very dangerous, don't try it at home nor at work. you don't want to play tag with a rabid man.

I'm sure someone will figure out how to flash the Mi50 bios on it. The question is if it's a software cap or a hardware cap.

The reasoning behind this is that the US government has mandated that manufacturers limit certain features to prevent them from being used as supercomputer components by competing governments. The US government has barred lots of chips from being sold to China which is probably why China's second most powerful supercomputer is using Ivy-Bridge chips. It's worth noting that since the US blocked sale of certain chips to China, the US has regained lead in supercomputer performance.

Because of this, it's almost for sure a hardware cap.

I'll weld the die back together.


Seriously though just like every AMD card they'll launch really high and end up really low. I'll buy one on sale with Wolfenstein for $400
Although with the memory bandwidth we may see a comeback for mining.

If that was the case the Titan, Titan Black, Titan Z, and Titan V wouldn't exist.

The embargo on chip sales to China is pretty broad, and only gets broader. Titan sales might already be blocked for China.

Thanks for confirming, yeah that looks to be the reason why. The Titan V is only available in the US and Canada.

but to answer his question seriously, i think they should look into promoting SLI NVLink more.
edit: on the other hand, i was under the impression that they were from Nvidia and talking about RTX... derp.

How about SRIOV?

AMD same as Nvidia cuts out all the "cool" features that enthusiasts would find interesting and leaves them to workstation/server cards only and asks even 10x price for those at times.

The US government business manipulation/wars are endless. Too scared and paranoid anyone else will be better by a hair. Well guess what, they already are, everything is made in China thanks to western governments not protecting local investments into manufacturing. China right now is on dark side of the moon, literally. Meanwhile US's space program is dead very dead, taken over by private sector. Forcing these blockades, tarifs and what not only hurts the one who issues them. Manufacturing of electronics will not move back to US because there is no "back", it was never made there (modern electronics, phones, PC parts, ...), they penalize imports from China... well they move to Vietnam, Taiwan, ... any nearby country that has a decent logistics connection so that they can keep using the same distribution channels and partners in south east Asia.
The technological fear of leaking anything from US is unreal, blocking specific technologies and even access to them in US itself if you want to work on them.
